摘要

本研究探讨职前小学教师在情境情境下,如何运用情境知识来模拟及解决八个算术运算结果有问题的问题。对参加数学内容课程的621名pet进行了纸笔测试。测试包括8个实验项目和4个缓冲项目。对97个pet样本的调查结果不太令人鼓舞。实际答案的总数从5到80不等(每个问题可能有97个答案)。总体而言,对8个问题的真实回答比例仅为31%左右。

Prospective elementary teachers’ use of contextual knowledge when solving problematic word problems
This study investigates the extent to which pre-service elementary teachers (PETs) use their contextual knowledge to model and solve eight problems for which the result of the arithmetic operation is problematic, if one takes into consideration the reality of the context. A paper-andpencil test was administered to 621 PETs enrolled in mathematics content courses. The test included eight experimental items and four buffer items. The findings for a sample of 97 PETs are not very encouraging. The total number of realistic responses varied from 5 to 80 (out of 97 possible for each problem). Overall, the percentage of realistic responses on the eight problematic items was only about 31%.
